# Overview

# InfluxData line-protocol flavor
|
||||
|
||||
## Overview
|
||||
|
||||
ClusterCockpit uses the [InfluxData line-protocol](https://docs.influxdata.com/influxdb/v2.1/reference/syntax/line-protocol/) for transferring messages between its components. The line-protocol is a text-based representation of a metric/event with a value, time and describing tags. All metrics/events have the following format (if written to `stdout`):
|
||||
|
||||
|
||||
```
|
||||
<measurement>,<tag set> <field set> <timestamp>
|
||||
```
|
||||
|
||||
where `<tag set>` and `<field set>` are comma-separated lists of `key=value` entries. In a mind-model, think about tags as `indices` in the database for faster lookup and the `<field set>` as values.

|
||||
|
||||
**Remark**: In the first iteration, we only sent metrics (number values) but we had to extend the specification to messages with different meanings. The below text was changes accordingly. The update is downward-compatible, so for metrics (number values), nothing changed.

In ClusterCockpit we limit the flexibility of the InfluxData line-protocol

slightly. The idea is to keep the format evaluatable by different components.

### Mandatory tags per message
|

|
||||
|
||||
|
||||
## Mandatory tags per message:
|
||||
* `hostname`
|
||||
* `type`
|
||||
- `node`
|
||||
- `socket`
|
||||
- `die`
|
||||
- `memoryDomain`
|
||||
- `llc`
|
||||
- `core`
|
||||
- `hwthread`
|
||||
- `accelerator`
|
||||
* `node`
|
||||
* `socket`
|
||||
* `die`
|
||||
* `memoryDomain`
|
||||
* `llc`
|
||||
* `core`
|
||||
* `hwthread`
|
||||
* `accelerator`
|
||||
* `type-id` for further specifying the type like CPU socket or HW Thread identifier
|
||||
|
||||
Although no `type-id` is required if `type=node`, it is recommended to send `type=node,type-id=0`.
|
||||
|
||||
### Optional tags depending on the message:
|

#### Optional tags depending on the message
|
||||
|
||||
In some cases, optional tags are required like `filesystem`, `device` or `version`. While you are free to do that, the ClusterCockpit components in the stack above will recognize `stype` (= "sub type") and `stype-id`. So `filesystem=/homes` should be better specified as `stype=filesystem,stype-id=/homes`.

### Mandatory fields per measurement
|

|

- Metric: The field key is always `value`
|

- Event: The field key is always `event`

There exist different message types in the ClusterCockpit ecosystem, all

specified using the InfluxData line-protocol.
